INTEGRAL represents a unique line of products featuring simple forms with narrow frames and a fixed glazing impression that creates a striking visual effect. This innovative design achieves the appearance of a single continuous frame, similar to fixed windows, giving the window an uninterrupted, monolithic look. The system profiles were developed without a visible slant, resulting in crisp external right angles that emphasize clean, contemporary aesthetics.
The use of an additional welded gasket in the frame profile significantly increases the overall tightness of the construction, resulting in exceptional water resistance with E1200 classification, as verified by IFT Rosenheim testing. This modern, single-frame visual form fits perfectly with the newest trends in architectural design utilizing glass, concrete, aluminum, and steel. The system profiles can be ordered in the form of welded or punched frames for maximum installation flexibility.
